Question

Calculate the mass percentage of each component when 10g of urea is dissolved in 90g of water

Answer 1

Answer:

Urea = 10%

ware=90%

Explanation:

Total mass of solution = mass of urea + mass of water

= 10g + 90g

= 100g

Now,

Mass per cent of urea = 10/100*100

= 10%

Mass per cent of water = 90/100*100

= 90%
